Introduced in this edition are three new scales (Insecure Attachment, Somatic Preoccupations, and Suicidality) and two new subscales (Hyperarousal and Other-Directedness). The four TSI-2 summary factors are either new to this version or have been reconfigured based on newly added or modified scales.

New items were introduced to the TSI-2 validity scales in order to assess a client’s tendencies to deny symptoms that are commonly endorsed, to overendorse unusual or bizarre symptoms, or to respond in an inconsistent or random manner. The Atypical Response validity scale was redesigned to assess not only overreporting in general, but also potential misrepresentation of PTSD.

TSI-2-A

The alternate 126-item version of the form does not contain any sexual symptom items—the Sexual Disturbance scale (i.e., the Sexual Concerns and Dysfunctional Sexual Behaviour subscales) and the sexual symptom items associated with the Externalisation factor have been removed.

Eight critical items help you identify issues or behaviours that potentially represent severe psychological disturbance, danger to the respondent, or danger to others.

Reliable change scores are new to this edition of the measure and allow you to track progress and monitor change over time.
